The function and advantages of the various components are further explained by illustrating the process of positioning the diamond table 1 by means of the diamond table 1 positioning device.

Firstly, as shown in fig. 2, 6 and 7, a diamond grinding disc 1 is clamped by a first group of pneumatic claws 5b in a manipulator 5, and a diamond grinding block 1b in the diamond grinding disc 1 faces upwards; when the diamond grinding disc 1 is placed on the bearing surface 4b1 of the positioning disc 4b, the magnetic piece 4g is attracted with the diamond grinding disc 1. The manipulator 5 is controlled to act and a piston rod of an operating cylinder 5c extends out; the diamond grinding disc 1 moves from top to bottom until the top surface of the convex body 4h abuts against the upper disc surface of the disc body 1 a; in this state, the projection 4h and the through hole 1d are in a dislocated state; the diamond grinding disc 1 has a movement tendency to move downwards and attach to the bearing surface 4b1 under the action of magnetic force and the thrust of the air cylinder 5 c. During the above-described placement of the diamond segments 1, the guide slopes 4f1 of the positioning claws 4f can correct the position of the disk body 1a slightly off-center; ensuring that the diamond grinding disc 1 is placed in the space between the positioning claws 4f and the outer side surface of the disc body 1a depends on the inner side surfaces of the positioning claws 4 f; meanwhile, the connecting column 1c is embedded into the positioning hole 4 e; thereby limiting movement of diamond abrasive disc 1 along bearing surface 4b 1.

Next, the first set of pneumatic claws 5b is held in a clamping state, the second motor 8 is controlled to operate, the second motor 8 drives the rotating shaft 4c to rotate through the second gear 9 and the first gear 4d, the rotating shaft 4c drives the positioning plate 4b to rotate, so that the convex body 4h rotates relative to the diamond grinding disc 1, when the convex body 4h is aligned with one of the driving through holes 1d, the diamond grinding disc 1 automatically moves downward by the magnetic force and the thrust of the air cylinder 5c until the upper disc surface of the disc body 1a abuts against the bearing surface 4b1 of the positioning plate 4b, as shown in fig. 8.
